The AtlasIED PA40G is a compact 40-watt single-channel power amplifier designed for commercial paging, background music, sound masking, and distributed audio systems. It provides 40 watts of output for 70.7V and 100V speaker systems in a space-saving 1RU, half-rack-width chassis.
The PA40G includes both balanced line-level and summed unbalanced RCA inputs, allowing common commercial audio sources to be connected without unnecessary system complexity. A universal 100–240VAC, 50/60Hz power supply supports installation in a wide range of commercial AV environments.
Removable level controls with a security cover help prevent unwanted adjustment after installation, making the PA40G well suited for permanent sound systems in offices, retail stores, restaurants, educational facilities, and other commercial spaces.
40W Output for 70.7V and 100V Systems
The PA40G delivers 40 watts of output power for distributed 70.7V and 100V loudspeaker systems.
This makes it a practical choice for smaller commercial systems using multiple transformer-equipped ceiling, surface-mount, or paging speakers.
The amplifier can be used for applications such as:
- Paging
- Background music
- Sound masking
- Retail audio
- Office audio
- Small commercial distributed sound systems
Balanced and Unbalanced Audio Inputs
The PA40G provides flexible connectivity for common commercial audio sources.
A balanced line-level input uses a Phoenix-style connector for integration with professional and installed audio equipment.
A summed unbalanced RCA input provides convenient connectivity for consumer and commercial line-level sources.
Secure Level Control
The PA40G includes a removable level control with a protective security cover.
Once the system level has been properly adjusted, the control can be secured to help prevent accidental or unauthorized changes—a useful feature for permanently installed commercial audio systems.
Status LEDs provide visual indication of amplifier operation for convenient system monitoring.
Compact Half-Rack Design
The PA40G uses a compact 1RU, half-rack-width chassis, allowing it to fit into installations where equipment space is limited.
For installation in a standard 19-inch equipment rack, the PA40G is compatible with the AtlasIED PA702-RMK rack mount kit.
